Police say the suspect is a 6-foot-tall black man with a heavy build, wearing a dark-colored jacket, light-colored sweatpants and dark gym shoes. He also had a hood or mask covering his face and was wearing gloves.

The Three Rivers Police Department has released a surveillance photo of the suspect in hopes of identifying him.

The incident took place about 10:20 p.m. Tuesday at BP Gas Station, 715 W. Michigan Ave.

According to a news release issued Wednesday afternoon, the suspect flashed what appeared to be a handgun covered in a red or pink towel. The man then bound the clerk's hands and feet and left him in the back office.

The suspect then stole an unknown amount of money from the cash register, took the clerk's cell phone and car keys, police say. He drove off in the clerk's car parked outside the store, according to the release.

Indiana State Police pursued the stolen vehicle on a toll road, until it reached the state of Illinois. The car was later found abandoned on the Chicago Sky Bridge. Police say the suspect might have called in a false 911 report prior to the robbery to lure police from the area.

Police ask anyone with information on this incident to call Three Rivers Police Department at 269-278-1235.
